We rented Airbnb suite listed as no smoking in house rules but upon arriving to go to sleep on night 1 of 3 night stay, entire house smelled of smoke and entire suite was taking on cigarette smoke from host smoking in bedroom below our suite. We contacted Airbnb as well S host. Host did not reply. We had to vacate premises immediately because smoke was so heavy. We could not breathe. Because she is a superhost Airbnb is allowing her to refuse refund.
